For this project, we used a bidirectional DC motor and solenoid valves to turn an ordinary Lazy Susan into a rotating platform system that could move a glass under inverted bottles and dispense liquids in a controlled manner, in order to make mixed drinks. Movement and liquid flow were controlled by an Atmel Mega1984 microcontroller, which was programmed using C software written in AVR Studio4, and the position of the glass was tracked by an Infrared (IR) sensor and feeback control loop. Drink orders are placed via a push-button menu. Ultimately, we were able to successfully implement our design for a menu consisting of five different non-alcoholic drinks: cherry coke, coke & lime, coke-sprite, Arnold Palmer, and Shirley Temple.
